Power Outage (vaguely planned, for once)
So repair guys are here to fix our power cable. In order to do that they need to take our power down. Estimated repair time is about 2-4 hours (there are "lots of obstructions" in the yard), which is probably more than the UPS can handle.
So, expect downtime. Probably within about 15 minutes of this posting to whenever (you can do the math).
Update 1pm: I'm a bit disturbed that they left without saying anything and there are no obvious holes in the yard, but the power is back and the Magic Portable Transformer Box is gone, so either it's all fixed or they've put on a much more clever (and much more hidden) temporary fix. I guess we'll see how this goes.
